Normal and Spec Behavior

by Brian Mayberry · in Torque 3D Professional · 08/19/2010 (12:55 am) · 1 replies

Hey gang, just posting this to see if I may be missing something with regards to normal and spec maps on collada files. I created this sea shell using 3Dmax 9, normal map generated with projection from a high poly model. This is the first time I've utilized this technique so I might have overlooked something simple.

Basically the specular highlight is not rendering the way I intend, you can clearly see once in T3D 1.1 b2, there is a banding of sorts that does not appear in my 3dmax viewport. Ideas?

Did some digging and this is a clear cut case of something simple I overlooked.

In 3D Max I had "Invert Y" enabled on my normal map. Going into Photoshop and inverting the green channel did the trick for T3D and now it's working exactly as I had hoped.

Cheers!
